Dec. 5, H p L ERG FOLDING MECHANI SM Filed Oct. 31, 1931 2 Sheets-Sheet l Dec. 5, 1933. p CLAUBERG FOLDING MECHANI SM Filed Oct. 31, 1931 2 Sheets-Sheet 2 INVENTOR E a AL;

ports to accommodate products of different thicknesses, and this is conveniently effected by spring mounting the rolls. One, suchmechanism is shown in which the sleeve or block 37 is provided with a spring 36' for the neck or stem 36. While this has only been shown at the center bearing, it will be understood that the sleeves 31, 44 may be similarly equipped if changes and variations may be made in the arrangement and construction of the invention, and the invention is therefore not to be restricted to the mechanism or arrangement shown.

What is claimed is:

1. In a folding mechanism, the combination of a folding cylinder, sheettaking devices carried thereby, means for holding a sheet on the cylinder after it has been released by the sheet taking devices, and means for adjusting the holding means circumferentially of the cylinder.

2. In a folding mechanism, the combination of a folding cylinder, sheet taking devices carried thereby, means for holding a sheet on the cylinder after it has been released by the sheet taking devices, and means operable while the machine is running for adjusting the holding means circumferentially of the cylinder. 7

3. In a folding mechanism, the combination of a folding cylinder, a folding blade, sheet taking devices carried by the cylinder, meansfor holding a sheet on the cylinder after it has been released by the sheet taking devices, and means operable while the machine is running for adjusting the holding means relatively to the folding blade.

4. In a folding mechanism, the combination of a folding cylinder, sheet taking devices carried thereby, means for rigidly holding a sheet on the cylinder after it has been released by the sheet taking devices, and means for adjusting the holding means circumferentially of the cylinder.

5. In a folding mechanism, the combination of a folding cylinder, sheet taking devices carried thereby, means for rigidly holding a sheet on the cylinder after it has been released by'the sheet taking devices, and means operable while the machine is running for adjusting the holding means circumferentially of the cylinder.

6. In a folding mechanism, the combination of a folding cylinder, sheet taking devices carried thereby, means for holding a sheet on the.

, a folding cylinder, sheettaking devices carried thereby, means for holding a sheet on the cylinder after it has been released by the sheet taking devices, means for adjusting the holding means to and from the cylinder, and means operable While the machine is running for adjusting the holding means circumferentially of the cylinder.

8. In a folding mechanism, the combination of a folding cylinder, sheet taking pins carried thereby, a plurality of holding members for holding a sheet on the cylinder after it has been re,-

leased by the pins, a shaft on which the holding devices are mounted, supports for the shaft, and means operablewhile the machine is running for moving the supports circumferentially of the cylinder.

9. In a folding mechanism, the combination of a folding cylinder, sheet taking devices carried thereby, a plurality of holding rolls acting I to hold a sheet on the cylinder, a shaft on which the rolls are mounted, a pair of arms supporting the shaft, and means operable while the machine is running forswinging the arms circumferentially of the cylinder.

10. In a folding mechanism, the combination of a folding cylinder, sheet taking devices carried thereby, a plurality of holding rolls acting to hold a sheet on the cylinder, a shaft on which shaft to and from the cylinder, and means for ioomoving the shaft circumferentially of the 7 cylinder.

.11. In a folding mechanism, the combination of a folding cylinder, sheet taking devices. carried thereby, a plurality of holding rolls acting to hold a sheet on the cylinder, a shaft on which the rolls are mounted, bearings forthe shaft, a second the shaft, bearings for the shaft, a second shaft supported in the arms,'connections from one of the bearings to the second shaft, and means for Y I holding devices to release a sheet, and means for adjusting the holding devices circumferentially of the cylinder.

14. In a folding mechanism, the combination of a folding cylinder, sheet taking devices carried thereby, holding devices acting to hold a sheet on the cylinder, means forrpermitting the holding devices to release a sheet, and means operable while the machine is running'for ad-' justing the holding devices circumferentially of the cylinder. 7
